SYDNEY — The Strait of Hormuz crisis has done something unusual. It has made visible a fact the modern economy usually hides in plain sight. Crude oil is not just fuel.
It is the raw ingredient for plastics, fertilisers, building materials, industrial chemicals, and pharmaceuticals. The ABC Science report makes this explicit.
A disruption in supply does not simply mean less petrol. It means the ingredients for medicines, car parts, and construction materials become more expensive. That is the core fact.
And it is a strange one. We talk about oil prices as if they only matter when we fill the car.
But the same barrel of crude that becomes gasoline also yields the building blocks for aspirin, for PVC pipes, for the nylon in a seatbelt. The Strait’s disruption will therefore send prices rising across a range of industries. The report lists them.
Plastics. Fertilisers. Building materials.
Industrial chemicals. Pharmaceuticals.
Consider medicines. Many pharmaceuticals rely on petrochemical feedstocks. Paracetamol, for instance, is synthesised from phenol, which comes from crude oil.
Aspirin starts with benzene. The list goes on.
A price spike in crude means a price spike in those feedstocks. That eventually means a price spike at the pharmacy. The report warns that the shock will keep pushing prices up in those sectors even if the Strait returns to normal.
The immediate spike in fuel costs is only the most visible symptom of a deeper vulnerability. That vulnerability is structural. The modern world is built on oil.
Not just for energy, but for the physical stuff of daily existence. The ABC report states that crude oil is a mixture of different substances, many of which enter the materials systems that underpin modern life.
The crisis has laid bare the extent to which economies are dependent on fossil fuels not merely for energy. The range of products affected is striking. Fertilisers are another example.
Ammonia production, essential for nitrogen fertilisers, uses natural gas as a feedstock. But natural gas and oil prices are linked.
A crude oil spike pushes gas prices up. That pushes fertiliser prices up. That pushes food prices up.
The economic ripples will filter through to a plethora of products, the report states. That suggests consumers should expect higher prices not just at the bowser, but at the pharmacy, the hardware store, and the supermarket. Australians are already feeling the fuel price shock at the petrol pump.
That is the visible symptom. The invisible symptom is the slow creep of costs through the entire supply chain.
A car part made of plastic becomes more expensive. A pipe made of PVC becomes more expensive. A pill made with petrochemical intermediates becomes more expensive.
The crisis has prompted questions about alternatives, but the ABC report offers no easy answers. For now, the dependence on crude oil as a raw material remains deep and broad.
What to watch next is whether this shock forces a reckoning. The Strait of Hormuz is a narrow waterway. A single disruption there has exposed a systemic risk.
The report does not predict what will happen. It simply documents the dependence. That dependence is the story.
It has always been there. The crisis has just made it impossible to ignore.
